It can be enjoyed on its own, or mixed with your regular coffee to reduce caffeine and acidity.
It's brewed just like coffee.
And can be served hot...
I can't say I loved it; you just can't beat good old coffee!! :P But as an alternative, it's pretty good. It looks like coffee, brews like coffee; really the only thing missing is the "caffeine".
I've also tried these coffee substitutes: Postum and Celestial Seasonings "Roastaroma" Of the three I think Roastaroma tastes the best and Teeccino is most like coffee. I just read that Postum has been discontinued! That's too bad!
I think it would be fun to compare all the substitute coffees and see which one is best.
